`this makes it necessari.1 to neeuro the door My invention relatos torotary weflhiugg machines, such es are used in large loundmee incl hasspecial reference to the oyln'uhrr doors of such machines end toimprovements v -upon the devices that are inA securing them in position.The chief members of e washer are, the cylindrical, shell sind theperforated, rotary cylinder, 'which isniountol within the shell. `Thecylinder .is usually alternately rotated to thoroughly agitato thegarments Within it and subject them to the action of the washing fluidin the shell.. The cylinder of the washing machine must be Strong, towithstand. the shochs end strains to which it is subjected, and this ieparticu`A larly true with repeet to that part of it which constitutes;the door. This door for the cylinder is usuell of greater width 'thanlength. It is hinged upon tliecylindr-i 'and 1s lprovided with latcheset ite tree edge to ho d rotated within the shell. The shell contain ini; is littlelargcr than the cylinfera und hinges and latches or lockstho. :we and compact. The hinges und intel washer cylinder doors, nethey have been used for years past, have been such that the been ofquite bursting open of the doom` has frequent occurrence, and the driving` mech-- anism used is of such power that the breeking of the doorlocks always rcsiulte in .Le

ItY ie neces sary that the latches, hingesand stops upon i The walls of cylinder doors shall be particularlyStrong yund effective, otherwise they will not sustain the blows uponthe door, the eHeet of ccntrifugol force thereon, sind other strains.the cylinder and the door as well are usually composed of Wooden stoves,and the only suitable laces for locks or latches are at the ends o thedoor whore the bolts may ,en age the metal hoops that are used for bining the Steves upon the heads of the cylinder.

The Stops.referred-to ure usually placed on the door itself and are nlctal partethat project from the free edge thcreo to strike or bear against theWooden. rib that frames the lower eide of the door opening. Thus nietulis made io heur upon Wood, und the frequent opening and cloning of thedoor (the door is '..ieuully slammed shut) causes the stops to sini; orweer into the wood to such an extent than. the outer fuer-.s of the doorbolts will nio longer stenti close against the inner Sides of thecylinder hoops. Thus it happens that a cylinder door which fits andlocks snugly when tiret put into use, quickly becomes will soon vibrateet every turn ov more-ment of the cylinder. ln other worde inet motionquickly develops ut the lern-e elige or end of the door, with the the'icm if4 euhiccted from the interior of the c vnlfm hier; :added to itthe momentum of i the door iteel l. until the capacity of the lock towithetund the blow is exceeded, und the door thrown or burst open,thereby allowing the gnrinciite to esca ie from the cylinder und heroineentangled upon the exterior tlnucol. or torn between the cylinder undthe shell. ,."llsoq when the door is burst open in this timonel. it. ingenerally broken by coni tuoi..

adequate hlm of the strain or weer upon the parte of a washing machinecylinder can be derived from mere obscrvtion of a. machine in operation,inasmuch as ythe cylinder is then in rapid rotation and is comp etelyhidden within the shell. 'I`his` doubtless accounts for the crudiiy ofthe fnetenings hithorto employed, for instellinge' (hat appear to heSuiicieutl) wrong und tight when the cylindcr ie stationary. developweaknesses when the cylinder le rotated. or lifter consider The ordinaryspringletch used on cylinder l able use.

The object ol' my invention is to improve the eonsl rut-lion ol rotarywashingr nnnfhines. and particularlyY to provid(l improved l': `leningsl'or the doors` ol' the wylintlt-rs ol sin'll machines.

A special olijwt olA any invention is to provide :i t'ylilnlersloorlatt'h that shall positivi-ly prevent vibration of the door, while theloths nre t-ngnged :ont uhith will finto inalienlly take up ihv .wnwear.

My invention uonsisls in the` volnhinulion of a washer t'ylinder and itsllrior with beiYY eletl top bolts upon thtlomz stops upon .said door,and stationary parts upon the` vylintler proper that are engaged by thestops and bolts, said bolts serving to draw said stops firmly together,und further, nly invention consists of an improved hinfe :1nd loeh forwasher cylinder doors, and it also consists in details of constructionand in tolnbirnition of parts :ill as hereinafter described and pointedont in the claims.

My invention will he more readily underA stood by refelenttto theaet'oinlnmying draw ings. forming' a wirt ol this specification, and inwhieh:n

Figure l is an elevation ot a. washing ninehine embodying' :nyintention, the shell lu:`- ing broken away to tlistlose the ':ylinderwith its hinges and latches. Fi if, is a transverse section on line ofFig. 1; Fig. 3, is a Side View of one of tht, hinges. Fig. 4, is anenlarged sectional View of ny in1- proved looking deriee, on line 3 ilof Fig. 1, showing the bolt and other partsn in lotlied position; andFig. 5, is a similar View showing the bolt partially withdrawn.,

As shown in the drawings, l represents the shell of the washing machine.This is a eylindrieal lub or vessel, having a suitable opening in itstop to permit neet-,ss to the t-ylinder, 2, which is arranged Within it.The ends, or heads, 4 of the shell are provided with bearings, 6, forthe gudgeons, 5, on the ends oi the cylinder. The cylinder, like theshell, is provided with a door openY ing, in order that the cylinder maybe readily filled with and emptied oflgurinents. The door openingrextends troni one head, 7, of the cylinder to the other. The slaves, 1l,are bound upon the heads, 7, by the hoops, 1S, 13, and thereforeportions of these hoops serve to frame the ends o'l' the door o Jening.The heavy ribs, 12, 12, are prefereb y used to frame the upper and lowersides of the door opening. Y

The door 1s composed of the stat/es, 8, like the Steves, 1l (butshorter) and the hinge leaves 9, the strives and leaves being boundtogether by a plurality of screws or bolts, 22. The staves andl'iinge-leaves therefore make up a rigid door, and as the leaves arecurved on the door it conforms to the curve of the rest of the eylinderand to the hoops, lo, thereon. The fixed leaves, 9, of the hinges areidentical with those forming parts ol the door and are bound upon thestares, il, ol the eylinder by screws or bolts sintilar to those used inthe door. The hinges at the oppositr ends are identital. Therefore onohinge pattern serves both, the two leaves of a hinge being of the suinelength, so that tht` hinge may be turned and have either oll its leavesfastened to the door. The hinges are preferably brass Castings, und asthis nieta! is oomparatively soit, it; nettes sary to lorni the hingesin suth a way as to gite them n'ntrirnnnl strength. To this end theleaves ol'` the hinges, except at the hinge points, have depressionswhereby each leaf is provided with a substantially Vertical flange orweb portion, SJ", that serves to stillen the lent'. [linge learns simplyturned up at` their outer edges possess sntlieient strength for thepurpose, but I go beyond such construction und provide eaeh leaf of thehinge with a horizontal extension or flange, 21, that overlaps theadjacent hoop. This flange performs two wry important oliees, first,itell'eetually closes the eraclc between the end oi the door and therylinder, preventing the estape ol small nrtieles, such as Collars orenll's lroln the cylinder; and second, it prorides a wide .strongr stopand bearing for the door, adapted to re'st upon the hoop. The llangeparts, Ell, upon the door leaves of the hinges are made to thus restupon the Curved hoops. when the door is closed, and in this manner l.provide strong and durableA tops for the door, which .stops will weer i`definitely und cannot be easily b1'oken,"even though u great l'oree isused in closing the door. A particular' advantage accruing from thiseonstruetitiin of the door and its hinves is thatvthere are no metalparts that strlke or bear against wooden parts of the cylinder, metal,at every point, being opposed to metal. There is, therefore littlelikelihood 0f the development of lost motion or looseness in the door.This being the cese, I am able to Secure the door by very sim le bolts,locks or latches. The locks or latelies are placed in the lower piece orstave of the door,whicl1 recessed to receive them.

1t) represents one of the latch cases which is preferably integral withthe hinge part. This is set into the recess of a stave, 8, and holds thebolt, 15, which has a shank, 16, en circled by a spring, 18, in saidease. The spring tends to force, the bolt outward. The outer end of theholt is held in the case by the hinge-leaf, 9, which bridges the recesscontaining the bolt.

19 is a finger-piece for withdrawing the bolt. The bolt is like untomost latches of the kind in all respects save that in addition to theusual beveled underside, 20, of steep pitrh, it is provided with a10W-pitched bevel or incline, 17, upon its upper or outer face.Referring to Figs. 4 and 5, it will be seen thus tightly und snuglysecures the door and prevents even slightY vibration thereof withrespect to the hoops and stoves ot' the eyl` inder. face of the bolt`insures` the taking up of all weer between the metal parts. The outerbevels of the bolts Cannot be lgreat and should never exceed ten tofifteen degrees. (lreuter inclination would render it neeessary to usestronger springs, making it dittienlt to withdraw the bolts to open (bedoor.

The essence of iny invention consists in the employment o1'l the metalstops upon the door to engage with the metal hoops. or like nieta! partsor stops upon the cylinder, taloui together with the wedgedike boltsadapted to draw such stops firmly together. This being the ease, I donot confine my invention to the specific constructions herein shown anddescribed.

Having thus described my invention, l claim as new, and desire to secureby Letters y Patent.:

l. ln it rotary washing Inaehine, the eyli inder, its hoops and its doorin combination with door hinges having leaves lapping uponV said hoopsand drawing bolts on the door to engage sald hoops and bind said leavesupon lt is obvious that the beveled outer them, substantially as and forthe purpose specified.

2. A rotary washer e Ylinder provided with a door openin frame at itssides by metal parte, in com ination with a door, hinges having verticaland horizontal flanges upon their leaves, said horizontal flanges bein`adapted to rest upon said metal parts and suitable door late les,substantially as and tor the purpose specified.

fi. The eombinution of a wooden cylinder, havingr metal hoops at .iteends, with a wooden door having metal flanges at its ends to engage saidmetal hoops, and elose the eran-ks between the door and the Cylinder'heads, and spring pressed bolts upon said door. said bolts havinginclined surfaces upon their outer ends to firmly wedge said metalflanges upon said hoops, substantially :is deseribed.

4. The eonibination of a wooden cylinder havin; r metal hoops at itsends,\vith a wooden door having hinges provided with flanges lappingupon `said hoops to elose the cracks between the door and the eylinderheads, und spring pressed bolts upon the door, said bolts havinginclined surfaees upon their outer ends to tirnlly wedge said metalflanges upon said hoops, substantiall)Y as deseribed.

In testimony whereof, I have hereunto set 1 my hand thisl 11th day ofliebruary, A. D.

1904. at Chicago, Illinois, in the preseneepf two witnesses.
